Page 5: Introduction
Advanced Radiant Systems’ unitary flagship is the Modulating Unitary Range (VA). The VA Range boasts the highest turndown ratio in the industry on a unitary heater. Unlike other manufacturers’ units, the VA Range modulates both fuel and air simultaneously for a true modulation benefit. By meeting building envelop heating demands on an ongoing basis, energy consumption is minimized. -

Page 14: Installation
INSTALLATION Installation Sequence Generally, there is no unique sequence for installation of the burner or heat exchanger. A review of the job site will usually indicate a logical installation order. However, time and expense can be saved if installation is begun at the most critical dimension, watching for interference from overhead doors, cranes, auto lifts etc. -

Page 16: Hangers Installation And Heater Suspension
INSTALLATION Hangers Installation and Heater Suspension • The suspension mechanism must allow for lateral tubing expansion. A minimum 12" length welded link chain with a working load limit of at least 200 lbs. is recommended (refer to Figure 7 for more details). -
Page 17: Tube Installation
INSTALLATION Tube Installation • Place the first (flanged, aluminized) tube in the first two hangers (Figure 9). Be sure the flange is toward the intended burner location. The other end of the tube should have the first coupling already loosely fitted. - Page 18 INSTALLATION • Tighten the cradle loops of the first hanger with the “J-Bolt” found in the burner box, to snugly hold the combustion tube from rotating see Figure 11. • • Note: For all coupling joints, ensure that the tube joint is in the center of the coupling length, and that the overlap joint of the coupling is above the centerline of the tube.
-
Page 19: Heater And Baffle Installation
INSTALLATION Heater and Baffle Installation • Locate the burner gasket provided, bolt the burner in place on the tube flange with provided hardware. Burner must never be installed in a tilted position. The sense electrode of the burner cup should be in the 12 o’clock position (Figure 12). - Page 20 INSTALLATION • If required for your heater model (refer to Table 1), install the baffle at the end of the heat exchanger. The small tab on the baffle is folded over the end of the tube and clamped in place by the vent connector and vent system, (refer to Figure 13).

Page 21: Reflector Installation
INSTALLATION Reflector Installation • Slide a reflector section into place within the support hanger, (Figure 14). SLIDE REFLECTOR THROUGH THE HANGER AND REFLECTOR SUPPORT AS SHOWN NOTE: CLOSE ALL CHAIN LINKS "S" HOOKS, QUICK LINKS AND TURNBUCKLES OR ANY OPEN CONNECTION Figure 14: Reflector Installation •... - Page 22 INSTALLATION Note: Reflectors should overlap adjacent reflectors 4" to 6". Be sure not to tile reflector sections; that is, reflector sections must be either above both adjacent reflector sections, or below both adjacent reflector sections. (Refer to Figure 16). REFLECTOR OVERLAP APPROX.
- Page 23 INSTALLATION • Secure every second reflector overlap together with a minimum of 2 - #8 x ³/8" inch long screws (not supplied), and secure reflector to the reflector bracket at this point by tightening down #8 x 1¼" screws supplied with reflector brackets (Figure 17). The remaining reflector overlap joints and reflector brackets are left loose to accommodate system movement.
-
Page 24: Elbow And U-Bend Installation
INSTALLATION Elbow and U-Bend Installation • If required by the heater layout, install 90° elbows or U-bend tubes where indicated. Refer to Figure 19 for details. • • Note: Elbows or U-bends are typically installed without reflectors. To reduce the above clearance to combustibles distance use miter reflectors (see Figure 18) and refer to Clearance to Combustibles information. -
Page 25: Side Reflectors & Bottom Shields
INSTALLATION Side Reflectors & Bottom Shields • If used, install side shields (reflectors) and/or bottom shield as required. Refer to Figure 21 and Figure 22 for details. • Side shields are 124" (315cm) long. Fasten one side shield per reflector with #8 x ³/8" screws. Use three side shield brackets per side shield. -
Page 26: Bottom Shield Reflector Installation
INSTALLATION Bottom Shield Reflector Installation • Bottom shields need not overlap. Each 5’ section is held with two support brackets (see Figure 22). NOTE: CLOSE ALL OPEN ENDED "S" HOOKS, QUICK LINKS, AND TURNBUCKLES OR ANY OPEN CONNECTION. TIGHTEN SCREW TUBING SECTION #8 X "... -
Page 27: Decorative Grille (Optional)
INSTALLATION Decorative Grille (Optional) ES/ESH Range heaters are approved for the addition of Decorative Grille either directly to the heater reflector or as part of a T-Bar installation where the heater is above the ceiling structure. Refer to Figure 23 and Figure 24 below for details. -

VENTING AND COMBUSTION AIR DUCTING Common Horizontal Venting • All heaters connected to a common horizontal vent must operate at the same time. Connect the electrical circuit to the same thermostat to ensure simultaneous operation. • Fresh air supply CANNOT supply other burner systems. •... -
Page 31: Vertical Venting
VENTING AND COMBUSTION AIR DUCTING Vertical Venting • Minimum vent pipe size is 4"(10cm) for an individual heater. Additional vent pipe sizes as required to accommodate multiple heaters venting through a common roof vent are defined in the appropriate gas installation code. -
Page 32: Combustion Air Supply (Optional)
VENTING AND COMBUSTION AIR DUCTING Combustion Air Supply (Optional) • An outside combustion air supply is strongly recommended if the building space encloses a negative pressure due to exhaust etc. or if the building contains materials which would expose the heater to halogenated hydrocarbon atmospheres. -
Page 33: Outdoor Installation (Esh Models Only)
VENTING AND COMBUSTION AIR DUCTING Outdoor Installation (ESH MODELS ONLY) When a heater is to be mounted outdoors it must be installed in such a way that wind will have minimum effect on its movement. This consideration is intended to eliminate undue stress on the gas flex connector. In all cases, a fresh air hood must be used in conjunction with a vent terminal of the approved type, and all connections must be sealed with a high temperature sealant that can withstand 400°F. -
Page 34: Electrical Wiring
ELECTRICAL WIRING General Requirements Heaters are normally controlled by modulating thermostats. In all cases, heaters must be grounded in accordance with the National Electric Code, ANSI/NFPA 70 in the US, and the Canadian Electric Code, CSA C22.1 in Canada, and must comply with all local requirements. Heaters may also be controlled with a manual line switch or timer switch potentiometer with or without timer in place of a thermostat. -

Page 37: Burner Operation
BURNER OPERATION Starting Sequence of Operation • Turn the thermostat up. When the thermostat calls for heat, both blower motors will energize • After the blower is running, the air-proving switch closes and activates the ignition module. • The ignition module, after a pre-purge period of approximately 30 seconds, energizes the igniter. Then, the gas valve is energized for this ignition trial period of 15 seconds. -
Page 38: Installation Checklist
INSTALLATION CHECKLIST Note: Complete checklist before lighting the heater. Correct any conditions that do not meet these instructions. Did you install the first hanger no more than 8 inches from the burner and tighten with the J-bolt? (J-bolt only required for the first hanger). Is the weld seam facing down? Is the tube system leveled? Did you mount the tube couplings with the band clamp lock bolts... -
